Matthew De Leon, 23, of the 4900 block of W. Eddy Street in Chicago’s Portage Park section, was charged late Tuesday with three felony counts of aggravated battery after being identified as the man who punched a 46-year-old female security guard at about 2 a.m. Sunday, according to the Chicago Police Department.

De Leon surrendered to police earlier Tuesday and said through a representative that “there are consequences he knows he has to face,” the Chicago Tribune reports.

“He knew what he did was wrong,” Dawn Valenti, a representative for De Leon, told the newspaper outside a police station. “I can’t tell you how sorry he is … He hit a woman. That’s not what he does.”

Valenti, a crisis responder for an organization called Chicago Survivors, said she knows De Leon’s family through a friend and agreed to drive him to give himself up to police.

“I did not condone what he did,” she told the Tribune.

Surveillance video outside a residential building in the 600 block of North Franklin Street in Chicago’s River North neighborhood showed an unidentified man punching security guard Zoa Stigler after she asked the man, who had just vomited, if he needed help.

The man, later identified as De Leon, then tossed a water bottle at Stigler and punched her in the face, causing fractures that may require surgery, she told WGN-TV.

“When he threw the water, I was shocked, I don’t even know what made me walk up to him,” Stigler told the station. “Why would you hit a human being in the face that is trying to assist you, trying to help you?”
